HIS. IN LESS THAN 15-HOURS, COLORADO BECOMES THE FIRST STATE IN THE NATION, ALLOWING THE LEGAL SALE OF RECREATIONAL MARIJUANA. BUT BEFORE NEW MEXICANS HEAD NORTH ACROSS THE STATE LINE ... THERE ARE SOME THINGS TO CONSIDER. IT'S NOT FAR FROM HERE,... TO POT'S NEW "PROMISED LAND." AND THAT'S THE RUB: EASY TO GET TO, AND EQUALLY EASY TO BREAK THE LAW. HERE'S WHAT YOU NEED TO KNOW: -FIRST: A PERSON MUST BE AT LEAST 21. -RESIDENTS OF COLORADO MAY BUY UP TO AN OUNCE. -OUT-OF-STATERS, ARE LIMITED TO A QUARTER OUNCE. -TO BUY MARIJUANA AND USE IT IN COLORADO IS LEGAL... -TO LEAVE COLORADO WITH IT IS ILLEGAL. THERE'S MORE: -YOU CAN'T RE-SELL IT TO ANYONE, -IT'S NOT LEGAL TO SMOKE IN PUBLIC, INCLUDING ANYWHERE WITH INDOOR AIR LAWS. -AND JUST AS WITH ANY INTOXICANTS, TOO MUCH AND YOU'RE IMPAIRED. AND LIKE DRIVING DRUNK... YOU CAN BE BUSTED. COLORADO VOTERS APPROVED ALL OF THIS. THIS NEWLY-LEGAL "PRODUCT," IS TAXED AT 25-PERCENT... PLUS MORE TACKED ON BY CITIES AND COUNTIES. THE WORLD IS WATCHING. "It could be a combination of a Green Wednesday ... and a Black Friday." DURANGO WILL EVENTUALLY BE THE COLORADO TOWN CLOSEST TO NEW MEXICO, TO SELL RECREATIONAL POT. BUT THAT WON'T HAPPEN UNTIL OCTOBER. THAT LEAVES PUEBLO AS THE NEAREST, COLORADO CITY WITH MARIJUANA FOR SALE, STARTING AT 8:00 AM TOMORROW. THE STATE OF WASHINGTON ALSO LEGALIZED POT.
